Description

CROSS REFERENCE TO A RELATED APPLICATION

This application claims priority to a Canadian Plant Breeder's Rights Application No. 21-10460 filed on Apr. 15, 2021, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein.

Botanical classification: Nandina domestica.

Variety denomination: ‘Nansid11’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nandina domestica and will be referred to hereafter by its cultivar name, ‘Nansid11’. ‘Nansid11’ is a new cultivar of heavenly bamboo shrub grown for use as a landscape plant.

The new cultivar was discovered by the Inventor in spring of 2016 as a naturally occurring branch mutation of Nandina domestica ‘Gulf Stream’ (U.S. Plant Pat. No. 5,656) that was growing in a container at his nursery in Mission, British Columbia, Canada.

Asexual propagation of the new cultivar was first accomplished under the direction of the inventor by tissue culture of meristematic tissue in spring of 2017 in Mission, British Columbia, Canada. Asexual propagation by tissue culture has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Nansid11’ as a unique cultivar of Nandina.

• • 1. ‘Nansid11’ exhibits new growth that is yellow in color.
  • 2. ‘Nansid11’ exhibits a dwarf, compact and densely branched plant habit.

‘Gulf Stream’, the parent plant of ‘Nansid11’, is similar to ‘Nansid11’ in growth rate and plant habit. ‘Gulf Stream’ differs from ‘Nansid11’ in having foliage with new growth that is more green in color. ‘Nansid11’ can be most closely compared to the cultivar ‘NanSid6’ (U.S. Plant Pat. No. 29,798). ‘NanSid6’ is similar to ‘Nansid11’ in growth rate and plant habit. ‘NanSid6’ differs from ‘Nansid11’ in having foliage with new growth that is red in color and in having finer (less wide) foliage.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The Applicant asserts that no publications or advertisements relating to sales, offers for sale, or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor. The Applicant claims a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date. Disclosures include but are not limited to website listings by Briggs Nursery, BC landscape Nursery Association, Sidhu & Sons Nursery, and Plantsomething BC.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color photographs illustrate the overall appearance and distinct characteristics of two year-old plants as grown outdoors in 1-gallon containers in St. Thomas, Ontario, Canada.

The photograph in FIG. 1 illustrates the overall plant habit and foliage coloration of ‘Nansid11’.

The photograph in FIG. 2 provides a comparison of new growth coloration between ‘Nansid11’ (left) and ‘Gulf Stream’ (right).

The colors in the photographs are as close as possible with the digital photography techniques utilized and the color values cited in the detailed botanical description accurately describe the colors of the new Nandina.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of a 2 year-old plants of the new cultivar as grown outdoors in 1-gallon containers in St. Thomas, Ontario, Canada.
